Well this is only my second ciritique, so sorry if it ends up not being very helpful.Anyway I really like the way you captured that reflection Though maybe if the lighting would have been a little better it would have a stronger impact. (But that is hardly your fault, so not much YOU could change when you're outside)But I really like how strong the colors are and how amazingly well you can see the rainbow pattern, even though it's reflected from your bicycle onto your hand, usually the colors fade a lot more.Also I'd suggest warming your hands up they look a bit frosted haha All in all it's a very great moment you captured.

It's clever! Wouldn't've thought of doing something like this. I think the impact could be heightened with a different angle, like tilted more so it's not exactly dead center. Also yeah the radial blur isn't doing it for me but I think the texture could be distracting too.
